Apparently the owners had moved into a hotel because of a fault with the furnace potentially allowing gas to reach catastrophic concentrations.

Ok, if that was a problem, why wasn't the gas shut off & neighbors made aware?

My daughters neighbor has gas, she does not. Her home has a carbon monoxide reader, because her neighbor had a gas leak. All the surrounding neighbors were made aware, and installed readers. My point: If it was bad enough to make them rent a hotel room...this would have been known by neighbors. It's just common sense.

Just FYI (in the interests of safety) a carbon monoxide reader is of no use in a gas leak.
